Microsoft Exchange 2013 shows blank ECP & OWA after changes to SSL certificates

This issue is described in KB2971270 and is fixed in CU6. I ran a couple of times in this error. After applying changes to SSL certificates (add, replace or delete a SSL certificate) and rebooting the server, the event log is flooded with events from source “HttpEvent” and event id 15021. The message says: An error occurred while using SSL configuration for endpoint 0.0.0.0:444. The error status code is contained within the returned data.

DataCore mirrored virtual disks full recovery fails repeatedly

Last sunday a customer suffered a power outage for a few hours. Unfortunately the DataCore Storage Server in the affected datacenter weren’t shutdown and therefore it crashed. After the power was back, the Storage Server was started and the recoveries for the mirrored virtual disks started. Hours later, three mirrored virtual disks were still running full recoveries and the recovery for each of them failed repeatedly. Patrick Terlisten/ vcloudnine.de/ Creative Commons CC0

Windows guest customization fails after cloning a VM

Last week I got a call from a customer. The customer has tried to deploy new Citrix XenApp servers, and because the VMware template was a bit outdated, he tried to clone a provisioned and running Citrix XenApp VM. During this, the customer applied a guest customization specification to customize the guest OS (IP address, hostname etc). Until this point everything was fine. But after the clone process, the guest customization started, but never finished.

HP StoreOnce: Avoid special characters in NAS share description

While I was playing with my shiny, new HP StoreOnce VSA in my lab, I noticed a curious behavior. I created a NAS share for some tests with Veeam Backup & Replication. Creating a new share is nothing fancy. You can create a share in two ways: using the GUI, or using the CLI So I created a new share: Patrick Terlisten/ vcloudnine.de/ Creative Commons CC0 Nothing special, as you can see.

VCP6-DCV Delta Beta exam experience

Today, I took my very first VMware beta exam. I took the 2V0-621D exam, known as the VMware Certified Professional 6 – Data Center Virtualization Delta Beta Exam, at a local Pearson VUE test center. This exam is a possible migration paths from a valid VCP5-DCV, or any valid solution track VCP, to the VCP6-DCV certification. The benefit of a beta exam is the low price (currently 50 US-$) and a chance to upgrade the associated certification, in this case the VCP6-DCV.
